2 Claims' (Cl. 233-24) This invention relates to centrifugal separators,and an object of the invention 'is to provide'a separator which willseparate heavy or unclean liquid containing foreign matter fr m lighteror 5 cleaner liquidby centrifugal action.

5 of a partition 1.

A rotor 8 is rotatably mounted in the casing I inany suitable mannersuch as by means of shaft ends!) and I and suitable bearings H.

The rotor 8 comprises a cylindrical body I 2 3 having a liquid orpropelling wheel I4 on one end thereof which is positioned adjacent tothe inlet M has vanes l5 therein so that the fluid flowing into thecasing I, under pressure, and engaging the wheel M will rotate the rotor8.

The liquid to be filtered or separated, after passing into the casing land through the liquid wheel l4, passes longitudinally through thecylindrical body l2 of the rotor where the centrifugal action set up bythe wheel I 4 will cause the lighter fluid to flow to the center and theheavy liquid orthe impurities in the liquid to flow towards theperiphery of the whirling column. The rotor 8 has a nozzle l 6 centrallylocated at its end remote from the liquid wheel M, which nozzle servesas an outlet for the lighter or clean liquid. The clean liquidpasses'from the nozzle [6 into the substantially cylindrical bodyl'l'from which it flows through. the outlet opening is into the chamberoutlet 4. v

The heavy liquid containing the impurities is picked up by a pumpimpeller i9 formed on the rotor concentrically of the nozzle I 6. pellerl9 forces the impure or heavy liquid outwardly through the chamber I9and outlet 3.

The cylindrical body 5 2 has a longitudinally ex- 5 and thence outthrough the distance from the longitudinal axis of the cylindrical bodyI2. The vane 20 facilitates the separation of the heavy or dirty fluidcontaining the impurities and the lighter or clean liquid.

It will be understood that the invention is not to be limited to thespecific construction or arrangement of parts shown, but that these maybe modified widely within the invention as defined by the claims.

What is claimed is:

1. In a centrifugal separator, a stationary casing having a pair ofspaced chambers thereon and a cylindrical portion connecting saidchambers, said casing having an outlet liquid, and an outlet for impureor heavy liquid, said latter outlet opening into one of said chambers, arotor in said casing including a hollow cylindrical body mounted withinsaid cylindrical portion and in sealed relation therewith, a propellerwheel at one end of said body and positioned in one of said chambers, animpeller at communicating with said casing outlet for light liquid.

2. In a centrifugal separator, a stationary casing having a pair ofspaced chambers thereon and a cylindrical portion connecting saidchambers, said casing having anoutlet for clean or light liquid, and anoutlet for impure or heavy liquid, said latter outlet opening into oneof said cham-. bers, a rotor in said casing including a hollowcylindrical body mounted within said cylindrical portion and in sealedrelation therewith, a proother chamber, a substantially cylindricaloutlet for, light liquid axially disposed opening into said rotor at oneend'and having an outlet communicating with said casing outlet for lightliquid, and a radial rib extending longitudinally in said cylindricalbody between said propeller and impeller. 4
